This is a continuation of application Ser. No. 08/379,162, filed Jan. 27, 1995, now abandoned.
The invention relates to novelty shoes, especially for children.
Shoes are fashioned to provide comfort and support, as well as to be aesthetically pleasing to the eye. For example, logos, stylized designs and decorative marks are often placed on the outer surfaces of the shoe.
Lights and sound-emitting devices have also been fixedly attached to or molded within a shoe to be sportive or amusing.
It has been known to attach display and other articles to the surface of shoe uppers. For example, Skaja U.S. Pat. No. 4,837,960 shows identification elements attached to a shoe by engagement of a peripheral mounting rib in a corresponding circumferential groove in the identification element. Skaja also mentions attachment of articles by means of VELCROŽ hook-and-loop type fasteners, e.g. as shown in Kellin et al. U.S. Pat. No. 5,136,726. Goria U.S. Pat. No. 4,712,319 describes shoes with detachable visibility aids held in place by spaced mounting appendages grasping the edge of a flange at the rear of the visibility aid. McGowan U.S. Pat. No. 3,114,982 describes an athletic shoe with weights in a removable case attached to the shoe upper with releasable snaps.
According to one aspect of the invention, an article of footwear comprises a shoe having a sole and an upper mounted on the sole, an ornamental article, and a snap attachment assembly comprising a female component fixedly secured to the upper of the shoe, the female component comprising a body portion formed of a resilient material and defining an attachment aperture, and an elongated cooperating male component having a body portion mounted to extend from a rear surface of the ornamental article and terminating in a tip portion spaced from the rear surface, the elongated cooperating male component sized for releasable snap fit engagement with, and disengagement from, the attachment aperture defined by the female component by application of axially directed force.
Preferred embodiments of this aspect of the invention may also include one or more of the following additional features. The elongated cooperating male component has a first diameter in the region of the tip portion and a second diameter relatively less than the first diameter in a region of the body portion relatively closer to the rear surface, and the attachment aperture defined by the female component of the snap attachment assembly comprises a through aperture with a first aperture portion having a third diameter selected for interference engagement with the tip portion of the second diameter, a second aperture portion having a fourth diameter greater than the second diameter of the tip portion, and a circumferential lip interface between the first aperture portion and the second aperture portion. Preferably, the first and second aperture portions and the lip are concentric. Also, the upper comprises an outer layer defining a display aperture, and the body portion of the female component of the snap attachment assembly comprises a disc-shaped member extending beneath the outer layer, with the attachment aperture exposed within the display aperture. Preferably, the female component of the snap attachment assembly is secured, with the disc-shaped member extending beneath the outer layer and the attachment aperture exposed within the display aperture, by stitching to the upper. The body portion of the female component of the snap attachment assembly further comprises a display member mounted upon the disc-shaped member and extending into the display aperture, the display member and the display aperture having predetermined complementary shapes.
According to another aspect of the invention, an ornamental article and display assembly comprises a shoe including a sole and an upper mounted on the sole, a plurality of ornamental articles, a fashion display accessory, and a snap attachment assembly comprising a first female component fixedly secured to the upper of the shoe, the first female component having a body formed of a resilient material and defining an attachment aperture, a second female component associated with the fashion display accessory, the second female component having a body formed of a resilient material and defining an attachment aperture, and an elongated cooperating male component having a body portion mounted to extend from a rear surface of the ornamental article and terminating in tip portion spaced from the rear surface, the elongated cooperating male component sized for releasable snap fit engagement with, and disengagement from, the attachment aperture defined by the first and second female components by application of axially directed force, whereby ornamental articles removably attached to the shoe and to fashion display accessory by cooperative engagement of the male and female components of the snap attachment assembly are interchangeable.
Preferred embodiments of this aspect of the invention may include one or more of the following additional features. The elongated cooperating male component has a first diameter in the region of the tip portion and a second diameter relatively less than the first diameter in a region of the body portion relatively closer to the rear surface, and the attachment aperture defined by the female component of the snap attachment assembly comprises a through aperture with a first aperture portion having a third diameter selected for interference engagement with the tip portion of the male component, a second aperture portion having a fourth diameter greater than the second diameter of the tip portion, and a circumferential lip interface between the first aperture portion and the second aperture portion. The fashion display accessory comprises a pendant and chain, a barrette or a bracelet. The fashion display accessory defines a plurality of display apertures.
Objectives of the invention include providing a structure for releasable attachment of display articles upon the surface of a shoe upper, and in particular upon the surface of children's shoes, the structure resisting dislodgement of the display articles during normal activities of running and jumping, but allowing easy removal of the display article by a child applying axial force. A further objective is to provide a set of display articles and complementary fashion accessories, the display articles being interchangeably displayed on the shoe and the fashion display accessories.
These and other features and advantages of the invention will be apparent from the following description of a presently preferred embodiment, and from the claims.
FIG. 1 is a perspective view of a novelty shoe of the invention with a side portion of the upper partially cut-away.
FIG. 2 is a front view of a female component of a snap attachment assembly of FIG. 1.
FIG. 3 is a cross-sectional side view of the female component of FIG. 2.
FIG. 4 is a rear view of the female component of the snap attachment assembly of FIG. 1.
FIG. 5 is a front view of a male component of the snap attachment assembly of FIG. 1.
FIG. 6 is a side view of the male component of FIG. 5.
FIG. 7 is a perspective view of a pendant having a snap attachment assembly.
FIG. 8 is a perspective view of a bracelet having a snap attachment assembly.
FIG. 9 is a perspective view of a barrette having a snap attachment assembly.
Referring to FIG. 1, a shoe 10 of the invention has a sole 11 and an upper 16, with one or more custom-designed ornamental charms 18 having a primary display surface 25. The charm is removably displayed on the outer surface of the upper, as described below. The shoe upper 16 is preferably canvas or leather, but may be formed of any other suitable material. A female component 12, which provides a base for attachment of the ornamental charms 18, is sewn with a portion extending beneath an outer layer 17 of the upper 16.
Referring now to FIGS. 2-4, female component 12 has a body consisting of a flat circular disk 14 having a predetermined thickness, e.g. 1.50 mm, and formed of a suitable, relatively resilient material, e.g. polyvinyl chloride (PVC) or polypropylene. Extending above an upper surface 21 (FIG. 2) of disk 14 is a secondary display portion display portion 20 having a heart shape exposed within an aperture 19 of complementary shape defined in the outer layer of the shoe upper.
The female component defines a through aperture 22 having a first, upper portion 23 of predetermined diameter, e.g. 2.6 mm, defined by a first encircling edge 27 sized for receiving, in snap-fit engagement, a corresponding member 34 extending from a rear surface 26 of charms 18 (FIGS. 5 and 6). The female component further defines a second, lower portion 28 the aperture, coaxial with upper portion 23, also having a predetermined diameter, e.g. of 6.0 mm, with a depth of about 2.0 mm measured from the bottom surface 30 of the disk. The interface between aperture portions 23 and 28 is defined by a circumferential lip or an encircling second edge 32, with the relatively larger radius of second aperture portion 28 providing flexibility to the lip to allow passage of the extension member 34 upon application of axially applied force (arrow A), while resisting displacement due to transversely applied forces, such as occurs during running and jumping.
Referring to FIGS. 5 and 6, an exemplary one of a variety of charms 18 is shown having a male component 33 in the form of the cantilevered member 34 extending from rear surface 26 of the charm. Cantilevered member 34 is formed of a suitable plastic, e.g. PVC or polypropylene, selected for stiffness similar to or slightly greater than that of disk 14 of the female component. Member 34 has a predetermined diameter approximately that of the through aperture 22, e.g. 2.60 mm, along a neck portion 38 (relatively closer to the base) and a second predetermined diameter, e.g. 3.20 mm, at a distal tip portion 40, the second predetermined diameter being selected to be slightly greater than the diameter of aperture portion 22 to provide an interference fit.
The geometry of the component pieces, and the resilient nature of the materials of fabrication, provide for secure attachment of the charm 18 to the shoe 10. Member 34 is pushed into aperture 22 of female component 12 by application of axially directed force (arrow A) so that distal tip portion 40 stretches aperture 22 until it "snaps" into aperture 28, thereby capturing male component 33 into female component 12.
Referring to FIG. 7, a pendant 44 defines a plurality of apertures (not shown), as described above, for receiving decorative charms 18 having corresponding male components. Pendant 44 is shown attached to a chain 46.
Referring also to FIGS. 8 and 9, a bracelet 48 and barrette 50, respectively, include female components 12, (e.g. molded-in or attached) for receiving charms 18.
Other embodiments are within the scope of the following claims. For example, disc 14 may be any flat shape, and may be attached to shoe 10, e.g., by stitching or adhesive. The female component 12 may also be secured to other parts of shoe 10, including the tongue and rear portions of the upper. The female component may have a body formed of a rigid material, e.g. hard plastic or metal, with a body portion insert of resilient material defining the attachment aperture.
It will also be appreciated that the invention may be employed with any of a variety of types of footwear, including, by way of example only, casual shoes, sandals, sneakers, hiking boots, rain boots and the like.
